30 designates one of the shafts on which the web-rolls are mounted. Rigidly secured on said shaft is a cone 31 and a gear 32. Fitting on the other end of the shaft is a cone 33, which may be made in the usual way in two split interlocking sections and which may be secured in place by means of a nut 34. This shaft 30-is inserted in the right-hand end of the web-roll, as shown in Fig. 2, the conesections 33 applied thereto, and the nut 34 then tightened up on the cone-sections, so that the web-roll will be nicely held and centered on the shaft 30.

35 designates a runway or guide formed on the end of each frame by which a fresh webroll W may bev rolled into the machine and slightly lifted to engage notches 36. From the notches 36 the frames are slightly inclined downward, as at 37, to form guideways or tracks, so that if the web-roll is lifted out of the notches 36 the same will run down said guideways and drop into notches 38, which notches 38 form the bearings for the web-roll when in the final operative position. Arranged in connection with each notch is a latch 39, which is adapted to engage the top of the shaft 30 when the same drops into said notches, and the head of the latch 39 is inclined, so that when the shaft 30 drops into said notches the same will move the latch to one side, so that the shaft 30 can automatically drop into its proper position. Springs 41 are used to keep the latches normally in engagement with the top of the shaft 30. A latch is preferably used on each of the two side frames. The latches are pivoted on suitable studs 40. Each latch connects by a link 42 to a handle 44, mounted on a shaft 43, which is fitted in the side frames 29 and which extends across the machine, so that by moving the handle 44 to the right the latches 39 can be disengaged from the shaft 30.

45 designates a gear which has conical or guiding flanges 46 46 on each side thereof. The gear and flanges are mounted on a shaft 47, which is journaled in a lug projecting down from one of the side frames 29 and also, if desired, in bracket 57. On the shaft 47 is arranged a brake-disk 48, cooperating with which are the two shoes 49 of a suitable brake. These shoes are hung on ashaft 54, the ends of which are tapped into the side frame and into the bracket 57, projecting therefrom. Secured on this shaft is asuitable hand-wheel 55 and a collar 56. By turning the handwheel 55 the gear 45 and its side flanges can be adjusted axially, and when the gear and flanges are adjusted axially in this manner the same motion .will be imparted to the gear 32, and thereby to the web-roll, which is in position, and by this means the slight axial adjustment sometimes necessary for the webtained as follows: When said hand-wheel 55 is turned, the shaft 54 is moved bodily either in or out. The brakeshoes 49 49 being loosely hung on the shaft 54 between said hand-w heel 55 and collar 56 will be constrained to move with said shaft. These brake-shoes fitting on said brake-disk 48 will move said brake-disk, and thereby the shaft 47 will be moved axially, and as the gear 45 and its flanges 46 46 are attached to said shaft 47 they will have to move therewith, and the flanges 46 46 will thereby adjust the gear 32. As the gear 32 is secured on the shaft 36 of the webroll, the web-roll will be moved axially. This adjustment is usually only a slight one and is provided for the purpose of bringing the web laterally or sidewise to proper position in the press. A shaft 50 is loosely mounted in bearings 52, and one end of the same isthreaded into one of the brake-shoes 49, and a collar 53 is secured thereon to bear on the other brake-shoe. Mounted on this shaft 50 is a hand-wheel 51. by turning which the bite of the brake-shoes 49 on the disk 48 can be adjusted. This brake is used to provide a resistance to the unwinding of the web, so that the web can be kept at the proper tension.

A feature'of the invention will be seen when it is noted that the fresh web-roll W will drop into its bearings 38, will be properly held therein by the latches 39, and as this action takes place the gear 32, which is connected with said web-roll, will also drop into position to properly engage the gear 45, and thus the braking device. The cone 31 may be grooved or notched, if desired, so as to obtain a good bite on the web-roll W.

The way the device is used is as follows: As the machine is in operation and while the operators have plenty of time a fresh webroll W is placed in the notches 36. The end of the web from this fresh web-roll is accurately cut or squared and the end thereof is doubled back and the same placed overthe tucker-blade 23, the pins 24 tightly holding the web on this crease. A line of paste is applied to the fresh web just below the crease and at the point indicated by 236 in Fig. 3. Considerable slack is then drawn off from the web-roll W and let out to the left, as shown in Fig. 7. This is all done while the machine is in full operation, the web in the machine being drawn from the expiring web-roll W, the parts then assuming the position shown in Fig. 7. When all the web that is desired is drawn from the roll W, the machine is put on its slow speed and the tucker 23 forcibly brought into the bite of the drum 16 and the roll 17. As the tucker is moved up the knife 26 will be brought into .position to bear on the web w drawn from the expiring web-roll W, and this web will be out off, as indicated in Fig. 8. At the same time the end of the fresh web w will be pasted onto the last end of the roll can be obtained. This adjustment is ob- 1 web w, and the pasted joint will be put under pressure by passing through the bite between the drum 16 and the roll 17 and the drum 16 and the roll 18. After this operation takes place the web w will then be drawn in from the drawing-in device, the tucker 23 of course being moved out of the bite as soon as the end of the fresh web w is pasted to the last end of the web w. The expired web-roll or stub W is then removed from the machine, leaving the parts as shown in Fig. 9. Then the web-roll W is lifted out of the notches 36 and given a push forward, when it will run down the guideways 37 and will drop into itsbearings 38, be held therein by the latches 39, and the gear 32 will engage the gear 15, and thereby the braking device. As the webroll runs down the inclines 37 it will be started turning in the proper direction, so that there willjbe no sudden pull put thereon as the web tightens between the drawing-in device and the web-roll. The operator of course properly manipulates the braking device so that the fresh web-roll will be properly started in action. All this can be done very rapidly and without stopping the machine, for just so soon as the pasted joint has been drawn through the machine at the slow speed the machine can be put back at full speed. Thus by this mechanism a great deal of time can" be saved.

Other forms of braking devices, adjusting devices, and bearings for the web-rolls may be used.
